What is the name of this 4-bit pattern: 1010 ?

A good answer might be:

A ― this is the name of the pattern the four bits make.

Base 16 Repn and 4-bit Pattern Names

The name of the pattern 1010 is the same as the hex digit that corresponds to the number represented by 10102.

When a 4-bit pattern is regarded as a number in (unsigned) base two, that number in hex is the same as the bit pattern name.

The name of a 4-bit pattern (regarded as an abstract pattern) is the same as the hexadecimal digit whose representation in binary is that 4-bit pattern. This is not accidental.


QUESTION 12:

Here is an integer represented in base two: 1011. What is the representation in base two of the number times sixteen?

Hint: remember that trick with appending zeros.
